DRAW ER LOCK;

sr'EoIFIcATfoN forming part of Letters Patent No. 732,971, dated July 7,1903.

Application died December 2,1902. Serial No. 133,561. (No model.)

' citizen of the United States, and a resident of Jersey City, in thecounty of Hudson and State of New Jersey, have invented certain new anduseful Improvements in Drawer-Locks, of which the following is aspecification.

Myinvention relates to drawer-locks of a class wherein the turning of asingle key or the movement of a single bolt serves to look a pluralityof drawers, shelves," or the like simultaneously; and its noveltyconsists in the construction and adaptation of the parts,

as will be more particularly hereinafter pointed out.

i In the drawings, Figure 1 is a front elevation of a series of drawersarranged in a frame and provided with my multiple lock, the lookingdevice being shown in dotted outline below and in section above, thepartsconcealing the latter being cut away to display it and the drawersbeing shown locked. Fig. 2 is a similar View showing the drawersunlocked. Fig. 3 is a central vertical transverse section of a drawerand adjacent parts, showing it unlocked. Fig. at is a. front elevation,partiallyin section, showing a modification of the locking device; andFig. 5 is a transverse vertical section through the lock, showing itsbolt lifted upward.

In the drawings, 4., 5, 6, and 7 are drawers arranged one above theother in a suitable frame, consisting of vertical side panels 8,horizontal partitions 8 .8 8, dad, between the drawers, a bottom 9, top9 and a suitable back. (Not shown.) The lowermost drawer is providedwith a lock and key of any improved form, provided the lock is of sucha. construction that its bolt 40 projects upwardly to lock the drawerand is retracted to unlock it. In Figs. 2 and 4 the front part of thedrawer is cut away to show the detail of the look. A recess 11 is cutaway from the lower side of the horizontal partition 8 immediately abovethe lower drawer 4 and is adapted toreceive the upwardly-projecting bolt40 of the lock. This partition 8 is also provided with a centralaperture in which is placed a sleeve 12, having an inwardly-projectingannular flange 13 at its lower end. Within this aperture and sleeve isloosely 4. The drawer 5 is likewise provided in front with a centralvertical aperture 5, at the top ofwhich is secured a sleeve 5 and nearthe lower part of which is secured another sleeve 5, flanged at 5 and inall respects like the sleeve 12 and flange 13 of the partition 8previously described. Within this aperture 5 is placed a rod 30, fittingloosely within the sleeves 5 and 5 and provided with a shoulder 31,adapted to rest upon the flange 5 and a downwardly-projecting pin 32,adapted to pass through the sleeve and projecting downward toward thepartition 8, which it almost reaches, but does not touch.

Supposing the parts to be assembled as shown in Fig. 2, it will beobserved that the drawer 5 is unlocked, because the rod 30, with itsdependent pin 31, is of such a length that The drawers 6 and '7 areprovided with central vertical apertures, sleeves, and reciprocatingrods similar to those described in connection with the drawer 5.Likewise the partitions 8 and 8 are provided with central verticalapertures and rods like the partition 8 just described. All of the rodsin the drawers and partitions are arranged in alinement, as shown inFig. 1.

Now if the key in the lock on the drawer 1 be turned so that the bolt 40of the lock is projected upward it will lift the dependent pin 22 so asto raise the rod 20 off of its seat on the flange 13. As the rod 20moves upward its upper surface will strike against the .lower part ofthe pin 32. This in turn will lift the rod 30 off of its seat,and itsupward surface will strike against the pin in the partition S ,which inturn will move the longer rod in the drawer 6, and so on, lifting eachrod upward, so that when it is attempted to remove the drawer forwardthe several rods engage with the sides applied to cases where two smalldrawers are 1 in g flan ge.

v the two rods of the drawer 6 beneath them,

as the larger drawer is locked by one such '20 and 20", placed withinrecesses 11 and 11 of the partitions and the drawers cannot be l movedfrom their places.

When it is desired to unlock the drawers, the key is turned in the lock,and the bolt 40 of the lock being thus depressed all of the differentrods and pins fall into place by the force of gravity, the annularflanges 18 5 850., preventing the rods from falling far enough to dropout of the several apertures provided to receive them. In the form of myinvention which I have illustrated and described all of the rods are inexact vertical alinement with the bolt of the lock on the lowermostdrawer. This is not necessary,provided a laterally-extendedbearing-surface is employed to transmit the motion from one lock and rodto the other. This modification enables the multiple lock to be placedabove a wider one, so that both of the small drawers are locked by twoor more upwardly-projecting rods in the same manner rod, and alsoenables two rods to be employed to lock the drawer-near its lateraledges. This modification is illustrated more particularly in Fig. 4. Inthis figure the same frame is shown as in Fig. land the same drawer 4,but the other parts are modified. Above the partition 8 are the drawers5 and 6 and above the latter two smaller drawers 7 and 7*, separated bya vertical partition 8. A recess 11, as before, is cut awayfrom thelower side of the partition 8 to receive the upwardly-projecting bolt 40of the look. This bolt is lifted and depressed by means of the key 4:1,pivoted upon the projecting rod 42. A guardplate 43 is set'in the drawerflush with thetop edge of the front panel. There is a central aperturein the partition 8" in which is placed the sleeve 12, but it has noinwardly-project- Instead of that the bolt 20 terminates in a wide plate25, which is provided on each side with two dependent guide-pins in thepartition 8. When the bolt 40 of the lock is moved upward, it strikesthe pin 22 and moves it upward and with it the rod 20 and the plate 25.Each of the drawers 5 and 6 is in this figure supplied with tworeciprocating rods and pins, the same being in vertical alinement, sothat the upward motion of the plate 25 transmitted to these rods willlock the drawers as before. The drawer 7 is, however, replaced by twosmaller drawers 7 a and 7", each of which is provided withvertically-reciprocating rods in alinement with so that lifting both ofthese rods locks each of these two small drawers in the manner alreadydescribed.

What I claim is,

1. The combination with a plurality of drawers or the like, eachprovided with a bolt normally held withinv one of its panels and all ofthe bolts in the series being in alinereae il ment, of fixed portionshaving recesses with which the bolts may engage in locked position,andmeans for moving all of the bolts simultaneously to lock the drawers.

2. The combination with a plurality of drawers or the like, eachprovided with a bolt normally held in its unlocked position within oneof its panels and all simultaneously returned from locked to unlockedposi tion by gravity when the lock is reversed, all of the bolts in theseries being in alinement, of means for moving all of the boltssimultaneously to lock the drawers.

3. The combination with a plurality of drawers or the like separated bypartitions, each drawer and partition being provided with a boltnormally held within a panel and all of the bolts in the series being inalinement, of means for moving all of the bolts simultaneously to lockthe drawers by moving the partition-bolts-into the drawer-panels and thedrawer-bolts into the partition-panels and holding them in place aftersuch movement;

4. The combination with a plurality of drawers or the like, of a seriesof bolts held within apertures in the corresponding panels of thedrawers and prevented by suitable stops from falling out of position, offixed portions having recesses with which the bolts engage in lockedposition, and means for simultaneously raising all of the bolts to lockthe drawers.

5. The combination with a plurality of drawers or the like, of a seriesof bolts normally held in unlocked position within apertures in thecorresponding panels of the draw ers and all of the bolts simultaneouslyreturned from locked to unlocked position by gravity when the lock isreversed, stops to prevent the bolts from falling out of normalposition, and means for simultaneously raising all of the bolts to lockthe drawers.

6. The combination with a drawer or the like provided with an aperturein one of its panels and mounted in a fixed portion having a recess inline with the aperture in the panel of the drawer, of a bolt adapted toreciprocate in said aperture held normally therein in unlocked positionand returned thereto by gravity when released from locked position, astop to prevent the bolt from falling out of its normal position, andmeans operated by a key to lift the bolt in its seat to cause it toengage the recess in the fixed portion and lock the drawer.

7. The combination with a plurality of drawers each provided withvertically-reciprocatin g bolts held normally in position to admit ofthe opening of the drawers, of fixed portions having recesses with whichthe bolts engage in locked position, and means for raising the lowermostbolt of the series whereby each bolt lifts its neighbor to lock thedrawer to which it is attached.

8. The combination with a plurality of IIO drawers and intermediatepartitions, each provided with vertically-reciprocating bolts heldnormallyin position to admit of the opening of the drawers, of means forraising the lowermost bolt of the series whereby each bolt lifts itsneighbor to lock the drawer to which it is attached.

9.: The combination with two drawers placed side by side each providedwith an aperture in one of its panels and both mounted a in fixedportions provided with recesses in placed side by side each providedwith. an ap-' erture in one of its panels and both mounted in fixedportions provided with recesses in line with the apertures in thedrawer-panels; of a bolt normally held in unlocked position in eachdrawer-aperture, a single drawer be} neath the two drawers, two bolts inthe lower drawer in line with the bolts of the upper drawers,connections between the bolts of the lower drawer, and means operatingon said connections for simultaneously moving the bolts of the drawersinto locked position.
